Description

Refrigerator with a refrigerator body Technical Field The present invention relates to a refrigerator. Background Generally, a refrigerator is an apparatus for refrigerating or freezing a storage object. Regarding the storage of refrigerators, a refrigerator is disclosed in prior patent publication nos. 10-2022-0084003 (hereinafter referred to as "patent document"; 2022, 6, 21). According to the above patent document, the refrigerator may include a cabinet forming a storage chamber, a heat exchange chamber formed inside the cabinet, an evaporator provided to the heat exchange chamber, a door opening and closing at least a portion of the storage chamber, a cabinet provided to the door and forming a storage space, and an air duct guiding cool air generated by the evaporator into the cabinet, extending from the heat exchange chamber and defining a cool air flow path connected to the door at a position closing the door. The air duct may include a first air duct extending forward along at least one wall of the inner case of the cabinet so as to be away from the heat exchange chamber, and the cabinet may include an inflow portion of cool air and an ejection portion of cool air. The refrigerator can cool the storage space of the box body by transmitting the cool air generated by the evaporator to the box body of the door through the air duct. However, the cold air generated in the evaporator is supplied not only to the storage chamber of the cabinet but also to the cabinet through the air duct, and thus there is a problem in that the circulation operation is varied. The air duct and the heat exchange chamber positioned at the lower part of the back surface of the cabinet are connected to the lower part of the side surface of the door, so that the cold air is difficult to be supplied from the lower part to the upper part of the door or difficult to circulate in the storage space. Further, the first duct is buried so as to extend toward the side of the door along at least one wall of the inner case of the cabinet, thereby having a problem of degrading the heat insulation performance of the refrigerator. Disclosure of Invention Technical problem to be solved The present invention has an object to provide a refrigerator having a structure capable of solving the above-mentioned problems. A first object is to provide a refrigerator having a structure capable of supplying cool air of a refrigerating compartment to a storage space inside a door. A second object is to provide a refrigerator capable of realizing a structure of temperature of a refrigerating compartment stage. A third object is to provide a refrigerator having a structure capable of preventing a reduction in heat insulation performance of the refrigerator by embedding an air duct using a separate cabinet. A fourth object is to provide a refrigerator having a structure capable of improving circulation of cool air so as to pass through a receiving portion inside a door without fluctuation of circulation operation. A fifth object is to provide a refrigerator capable of preventing a cooling fan mounted to a door from being exposed to the outside. Means for solving the technical problems The inventors of the present invention have found through intensive studies that the technical problems of the present invention and the first to fifth objects described above can be achieved by the following embodiments of the present invention. In order to achieve the above object, a refrigerator according to an embodiment of the present invention includes a cabinet having a storage compartment, a refrigerator door having a storage portion for opening and closing the storage compartment, and a cool air supply device for supplying cool air to the storage portion so that the cool air in the storage compartment circulates through the storage portion. The cool air supply device includes a cooling fan provided at the refrigerator door to suck cool air into the storage chamber, and a suction duct connected to the cooling fan and an upper portion of the receiving part to transfer the cool air sucked by the cooling fan to the upper portion of the receiving part. Thus, the cold air supply device can supply cold air to the storage part of the refrigerator door in a cold air circulation mode. According to an embodiment, the cool air supply device may be provided at an upper portion of the refrigerator door. Thereby, the cool air supply device can supply cool air of the storage chamber to the upper side of the storage part. According to an embodiment, the storage compartment includes a refrigerating compartment. The refrigerator door includes a first door having the storage portion rotatably mounted to the cabinet to open and close the refrigerating chamber, and a second door rotatably mounted to the first door to open and close the storage portion. Thereby, the cool air supply device can supply cool air to the storage part of the first door. According to an embodiment, the second door is
